Across the entire animal kingdom, visual images are processed by two major neuronal pathways that extract light and dark stimuli from visual scenes – ON (light on) and OFF (light off) pathways. Light ...

Researchers at the University of Helsinki have made a breakthrough in understanding what neural mechanisms allow the extreme sensitivity of human vision in darkness. The new research shows that humans ...

A wave of recent research has brought robotic touch sensitivity closer to human fingertips than ever before, driven by ...

Like most primates, humans are remarkably touchy-feely. Starved of touch, we release more of the stress hormone cortisol, which causes the immune system to be down-regulated and the heart rate and ...

Researchers have successfully developed an ultra-sensitive pressure sensor for electronic skin modeled after the nervous system in the human brain. This technology is applicable to future devices, ...
